At least one standard rolling bearing that has an outer race which is arranged in a bearing seat in a fixed position relative to the stator and which cooperates via a rolling body arrangement with an inner race arranged on a shaft of the rotor. The bearing seat is lined with an insulation arrangement in order to avoid a flow of current between stator and rotor, the insulation arrangement having a thin, sheet-type semifinished product having insulation material resistant to the radial pressure force of the bearing.
